If the <META name="robots"> tag is present and includes the data
"noindex", the page will not be index. The "nofollow" data will prevent
the spider engine from following any links found on that page. To prevent
a cached copy of the page being stored, include the "noarchive" data in
the robots META tag.

Use a robots.txt file to exclude iSearch from certain parts of your site.
See
http://www.robotstxt.org/wc/norobots.html for the specification of
this file. iSearch follows the rules for the "iSearch" user-agent. The
Google extension of "*" (wildcard match) and "$" (match end of line) are
supported by iSearch.

If the URL to a page begins with one of the strings in the
"Exclude URL(s) Beginning" configuration setting it will not be indexed.

If the URL to a page matches one of the regular expressions in the
"Exclude URL(s) Regexp" configuration setting it will not be indexed.

Part of a page can be excluded by placing the following HTML comments around the text:

<!-- ISEARCH_BEGIN_INDEX -->
<!-- ISEARCH_END_INDEX -->

These are used as follows:

The ISEARCH_BEGIN_INDEX and ISEARCH_END_INDEX comments must appear in pairs.

If the first ISEARCH_END_INDEX comment appears before the first ISEARCH_START_INDEX comment, the following body text will be excluded from the search index:

any part of the body of the page between the ISEARCH_END_INDEX and ISEARCH_START_INDEX pairs
